问题描述

如何测试对象是否具有特定属性?

How can you test if an object has a specific property?

感谢我能做到...

$members = Get-Member -InputObject $myobject 

然后foreach通过$members，但是有没有函数可以测试对象是否有特定的属性?

and then foreach through the $members, but is there a function to test if the object has a specific property?

附加信息:问题是我正在导入两种不同类型的 CSV 文件，一种具有两列，另一种具有三列.我无法让支票与属性"一起使用，只能与NoteProperty"一起使用......无论有什么区别

Additional Info: The issue is I'm importing two different sorts of CSV file, one with two columns, the other with three. I couldn't get the check to work with "Property", only with "NoteProperty" ... whatever the difference is

if ( ($member.MemberType -eq "NoteProperty" ) -and ($member.Name -eq $propertyName) ) 

推荐答案

喜欢这个吗?

 [bool]($myObject.PSobject.Properties.name -match "myPropertyNameToTest")
